Repeat Visits

A remotely controlled artificial flower system for investigation of bumble bee foraging behaviour in the laboratory is described. The behaviour of Bombus atratus Fkln. workers from captive colonies trained to forage on patches of artificial flowers in a flight room conformed well to the predictions of optimal foraging theory. Within-patch movement was systematic, tending to minimize repeat visits to flowers sampled previously. Between-patch movement was influenced both by frequency of encounters with empty flowers in the first patch and by inter-patch distance.

Early Phases

AbstractWorker-male conflict in different bumble bee species is strongly associated with tendency, toward inbreeding. It is hypothesized that the major cost imposed by inbreeding arises from the production of diploid males in place of workers, during the early phases of colony development. The consequent dilution of the labour force slows down colony growth and leads to ultimate reduction in reproductive success. An experiment to test this hypothesis is described, using consanguineously mated queens of B. atratus Fkln. Colonies yielding a 1:1 mixture of males and workers grew significantly more slowly than normal all-worker producing colonies, providing support for the hypothesis.
